A setting unit of a safety-device activation timing controlling apparatus sets a first timing upon it being determined that a driver's collision avoidance operation in a longitudinal direction has been carried out. The first timing is later than a reference timing for activating the safety device. The setting unit sets a second timing upon it being determined that a driver's collision avoidance operation in the lateral direction has been carried out. The second timing is later than the reference timing. Upon it being determined that at least one of the driver's collision avoidance operation in the longitudinal direction of the own vehicle and the driver's collision avoidance operation in the lateral direction of the own vehicle has been carried out, an activation determining unit determines whether to activate the safety device in accordance with a corresponding at least one of the first timing and the second timing.
